When Paul warned Titus about false teachers, he summed up their problem in one sharp sentence: “They profess to know God, but they deny Him by their works.” (Titus 1:16) The statement can be understood in two ways, and both fit. On one hand, Paul could be saying that their behavior—rebellion, greed, and deceit—betrayed their confession. On the other hand, he may be referring to their obsession with religious “works,” such as circumcision, as proof of righteousness. In either case, the message is the same: their lives, not their lips, revealed what they truly believed. When people rely on good deeds to earn God’s approval, they are not just mistaken—they are denying the sufficiency of Christ’s work on the cross. It is as though they are saying, “Nice try, Jesus, but I’ll finish this myself.” That kind of thinking not only misunderstands grace; it insults it. Salvation by self-effort is like trying to jump the Grand Canyon with a pogo stick—ambitious, perhaps, but doomed from the start.
The Galatians faced the same confusion when false teachers convinced them they could “improve” on grace. Paul challenged them bluntly: “Did you receive the Spirit by works of the law, or by hearing with faith?” (Galatians 3:2) They knew the answer—it was faith, not performance. Yet human nature still whispers, “Surely, I can do something to help.” Even the prodigal son, returning home in rags, offered to become a hired servant so he could earn his keep. The father, however, ignored that suggestion entirely and threw him a party instead. God’s love works the same way. He doesn’t want employees; He wants children. Yet we keep trying to clock in and impress the boss. We measure ourselves by checklists, rituals, and rule-keeping, forgetting that the point of the gospel is not better behavior—it’s new birth.
Arthur Pink captured it well: “It is not what we can do for God, but what God has already done for us.” When the Philippian jailer cried, “What must I do to be saved?” Paul replied, “Believe in the Lord Jesus Christ, and you will be saved.” (Acts 16:31) Jesus Himself defined “the work of God” as simply this: “to believe in the One He has sent.” (John 6:29) Our salvation rests not on what we accomplish, but on what Christ accomplished. As Paul wrote, “We know that a person is not justified by works of the law but through faith in Jesus Christ.” (Galatians 2:16) In other words, the only “work” worth trusting is the one already finished—nailed, sealed, and declared complete at the cross.
